摘要： A wafer cleaning method is provided. The wafer cleaning method includes providing a wafer on a stage that is inside of a chamber. The wafer is fixed to the stage by moving a grip pin connected to an edge of the stage. First ultrapure water is supplied onto the wafer while the wafer is rotating at a first rotation speed. The grip pin is released from the wafer by moving the grip pin. A development process is performed by supplying liquid chemical onto the wafer while the wafer is rotating at a second rotation speed that is less than the first rotation speed.
